The Q1 of 2023 has been one of critical milestones representing significant progress across the organization. These advancements have positioned Travir for sustained growth led by the ongoing launch of FilSparri in IgA nephropathy and bolstered by the continued progression of our pipeline. The most notable achievements in the quarter was the U. Speaker 200:02:09S. Accelerated approval of FilSpari or sparsentan for the reduction of proteinuria in adults with primary IgA nephropathy or IgAN at risk of rapid disease progression. The approval of TILSPARI marks the 1st and only non immunosuppressive therapy for the reduction of protein proteinuria in IgAN. While we are only in the early stages, the commercial launch is progressing very well and in line with our expectations. Today, we'll focus on the important takeaways from the 1st 6 weeks, but I am very pleased with the early demand and the commercial organization's execution, which instills confidence that we will effectively position TILSPARI to meet or exceed our internal goals for the year. Speaker 200:02:55Furthermore, we were very excited to see the interim results from the PROTECT study published in The Lancet. These data further elucidate the to the active control herbosartan. The compelling data sets support our confidence in a positive outcome from the 2 year secondary endpoints in the Q4 of this year. Overall, it was a great quarter for our efforts to establish the foundation for to become a new treatment standard in IgAN for the addressable population. Earlier this week, we were disappointed to report that our Phase 3 DUPLEX study of sparsentan and FSGS did not achieve the primary efficacy EGFR endpoints. Speaker 200:03:47FSGS is a very difficult disease to study. Despite this, sparsentan still managed to demonstrate a consistent profile characterized by sustained proteinuria reduction and a well tolerated safety profile over 2 years. We will continue to analyze the datasets and engage with the FDA and EMA to explore the With regard to pegmatinase, we continue to be highly encouraged by the forward momentum in our program for classical homocystinuria or HCU. As many of you will recall, HCU is a serious and progressive metabolic disorder that can lead to thrombotic events, Serious vision problems due to lens dislocations, bone malformation and a constellation of mental and psychiatric complications. Importantly, pegdevatinase is well positioned to potentially become the 1st and only disease modifying approach to treat HCU. Speaker 200:04:52We have made recent strides in our program and remain on track to report data from Cohort 6 in the 2nd quarter. We are incredibly grateful to the patients, family members and physicians who have supported us in our pursuit of therapeutic advancements for diseases Our team remains committed to our mission of improving the lives of those living with rare disease, delivering for our patients for the rare disease community and our shareholders. Now let me turn the call over to Jula for a clinical update. Jula? Speaker 300:05:28Thank you, Eric, and good afternoon, everyone. I'll start by highlighting our continued efforts to support the awareness and Education of the Filspari clinical profile. As Eric mentioned earlier, we were very pleased with the recent publication of the interim results from the Phase 3 PROTECT study in The Lancet. The rapid publication in this renowned journal speaks to the scientific relevance and strength of the PROTECT interim results in IgA nephropathy. The publication serves as a great platform to showcase the interim results from PROTECT, The largest interventional study of its kind in IgA nephropathy. Speaker 300:06:09The published results detail the rapid and sustained reductions of proteinuria Weeks of treatment in PROTECT. A significantly greater proportion of patients on FilSpari achieved complete and partial remission of proteinuria. As recently published, most high risk IgAN patients will face kidney failure within their lifetime, And reducing and maintaining lower thresholds of proteinuria, particularly to levels less than 0.5 grams per day can impact long term kidney outcomes. We also saw encouraging early trends on important kidney outcomes. Here approximately half the number of patients treated with VILSPARI reached the confirmed 40% reduction in eGFR from baseline, Kidney failure or all cause mortality compared to irvastatin. Speaker 300:07:14Furthermore, important data were included that support our belief And the primary efficacy objective of the Phase 3 PROTECT study that optimally antagonizing Endothelin 1 and angiotensin 2 with sparsentan may lead to protective effects in the kidney structure and function beyond hemodynamics. Specifically, the authors drew the conclusion that the proteinuria lowering effect of sparsentan is unlikely to be attributable to differences in blood pressure, especially given the large differences in proteinuria reduction relative to minimal differences in blood pressure. Finally, The publication also included additional safety data from the interim analysis, which reported no cases of heart failure at the time of the analysis, No treatment discontinuations or serious adverse events of peripheral edema and no significant difference in weight change between treatment arms. These published interim results and the preliminary eGFR data from the interim analysis and the clinical literature Demonstrating the relationship between proteinuria reduction and eGFR benefit support our steadfast confidence for clinically meaningful and statistically significant treatment effect on EGFR after 2 years of treatment with sparsentan. I'm pleased to report that the PROTECT study continues to accrue patient data as expected and remains on track for the scheduled top line readout in the Q4 of this year. Speaker 300:08:45Since Filspari's accelerated approval, We've also received solid support from the nephrology community, including physicians, patients and advocacy groups. Following a discussion with an academic nephrologist at NKF, I learned that the Lancet publication was the primary reason behind their decision to We are receiving similar anecdotes that physicians intend to alter the way that they treat their patients by including VILSPARI as a key treatment option now that it's available. Importantly, VILSPARI is now included in the treatment recommendation or switching the RAS inhibitor to Filspari. We eagerly look forward to the confirmatory Phase 3 PROTECT study data, which we believe will put us in a strong position to enable Filspari to become the new foundational therapy in IgAN. Since we recently hosted an update call, I'll only briefly touch on sparsentan's development in FSGS. Speaker 300:10:03While we were disappointed to report that the DUPLEX study did not achieve statistical significance on the EGFR endpoint, It did demonstrate consistent proteinuria reduction of 50% across studies. Importantly, we also saw that with a higher dose, Since we reported our results, we've had a chance to engage with both nephrologists and the patient community. The resounding feedback has been supportive and encouraging. This combined with the positive trends seen in the study further supports our motivation in seeking a path forward with regulators in both the U. S. Speaker 300:10:39And Europe. Beyond sparsentan, we continue to advance our Pegtobatinase program in classical homocystinuria. As many of you will recall, in the first five cohorts of our ongoing Phase onetwo COMPOSE study, Tectabatinase demonstrated a dose dependent response and ability to dramatically reduce total homocysteine to clinically meaningful levels with the 1.5 milligrams per kilogram dose. Importantly, pecovatinase was able to show a generally well tolerated In the 6th cohort, we're examining a higher dose and lyophilized formulation, which will give us valuable insights for the program's next steps and aid our discussions with regulators regarding the design of a Phase 3 study to potentially initiate in the second half of this year. Additionally, we've made recent progress on our manufacturing to support a pivotal program and commercialization. Speaker 300:11:47And so we look forward to sharing an update on those data later this quarter and plan to provide an update regarding next steps for the program later this year. With that, I'll turn the call over to Peter for the commercial update. Peter? Speaker 400:12:01Thank you, Zohar. I'm pleased to report that we are making great progress in the early days of sales party launch. Our results in the Q1 included only 6 weeks, and we are in line with our expectations. We are encouraged with the strong level of interest and engagements that we are seeing across stakeholders, including patients, physicians and payers. Let me reflect on our progress and share some of the metrics that we saw in the 1st week 6 weeks of approval until the end of Q1. Speaker 400:12:32Since our approval on February 17, we have remained focused on our 3 launch priorities, educating nephrologists Have a positive first experience with Phil's diary. 1st, looking at our physician education efforts, Our commercial field team of over 80 seasoned professionals is successful in getting access to nephrologists and educating them on the sales party label. Our strategy is to ultimately reach a universe of 6,000 nephrologists, representing roughly 85 We have face to face interactions with over 2,500 of these nephrologists in the first These engagements are aligned to our profiling insights, and we are reaching those nephrologists that have been And we believe we'll be the early adopters. The reception to Falspar's efficacy and safety profile has been strong. Physicians consistently mention the impressive proteinuria reduction with Trosparin and the importance of having the non immunosuppressive IgAN therapy. Speaker 400:13:51And we are excited to see a strong increase in brand awareness now that our team is actively discussing TOSPARI with nephrologists. As mentioned on the last earnings call, we received our 1st patient start forms on the 1st working day after approval, which was also the day that we started educating physicians about XERSPARRI and the first product was shipped to the patients the week after, Just 8 working days from approval. We heard from one of these early prescribers and anecdotally, With his first patients treated with TOSFARI over the 1st 6 weeks, he has observed a rapid proteinuria reduction consistent with what was These are the stories that energize our incredibly dedicated bonds team. This team is going steadfast in serving and educating our stakeholders. And it is encouraging that we are starting to hear how patients may be benefiting from Tversary Treatment. Speaker 400:14:54In the 1st 6 weeks, Travir Total Care received 146 patient start forms, And we see an increasing number of physicians getting involved in the REMS program as they have identified patients who can benefit from full styrene. Secondly, we are making robust progress in educating payers on IgAN as the leading bone marrow disease pause for kidney failure and that most IgAN patients progress to kidney failure within 10 to 15 years of diagnosis And the meaningful the meaningfulness of proteinuria is a prognostic indicator for disease progression. Within that context, Our in field account teams emphasizing Filsparis' compelling value proposition to the payers. As a result of these educational efforts, We are seeing Fiospiri is being discussed at P&T committees. And the first formularies In the 1st 6 weeks, We achieved 38% payer coverage of the U. Speaker 400:16:10S. Population. In the coming months, we anticipate coverage will continue to expand, We will periodically share our continuing progress. Similar to other newly approved therapies for rare diseases, Initial access to Filzpari is mainly through prior authorization and if denied through appeal processes. We are encouraged with the rate that patients are able to gain access. Speaker 400:16:38Since the claim Experience a slow or delayed communication process, we have support programs to provide eligible patients with access to products. Finally, our 3rd launch priority is providing iGAM patients, their caregivers and the treating physicians with a positive experience in It was designed with the patient in mind to offer easily accessible programs, including personalized education, assistance in the REMS process, Supporting the reimbursement process and co pay assistance for eligible patients. Initial patient feedback is rewarding as we hear through TRILIA Total Care about patients' appreciation for these offered services. Turning to Tralea Total Care, we designed and launched support services to streamline and simplify the REMS enrollment and implementation process for physicians and patients. We are hearing from nephrologists that the REMS process is straightforward. Speaker 400:17:46Hence, to my earlier point, We are seeing a significant number of physicians enrolling in the REMS program because they have patients identified that could benefit from TOSPARI. From a financial perspective, we finished the Q1 with Netfield Styrene sales of $3,000,000 It is important to note that this is predominantly based on the specialty pharmacies initial starting of the distribution channel. As you may recall, we utilize a small network of specialty pharmacies to maintain high services for our patients. One of these specialty pharmacies has multiple regional distribution centers that each elected to stop for the initial launch to be ready for demand. As a result of this, we anticipate that a meaningful portion of this stocking in the Q1 will be drawn down in the 2nd quarter and impact our Q2 revenue. Speaker 400:18:41We anticipate that it will begin to that we will begin to see a more representative trajectory of both demand and reimbursement in the Q3 and a clear view by the Q4. Overall, I believe that the launch is off to a strong start. We are seeing steady demand building. The initial metrics that I shared indicate the nephrology community's excitement of the Aspirus potential for IgAN patients. With the recent plans and publication of the PROTECT interim analysis, inclusion of Filspiri in the treatment guidance tool up to date, The personal experience that nephrologists are getting on the rapid and sustained proteinuria reduction with TILSTARI in their own patients And the number of nephrologists that are now involved in the REMS program gives me confidence that we will continue building the momentum. Speaker 400:19:37With respect to the commercial performance outside of SureSpire, I am really pleased how our team is continuing the strong execution in connection with our established commercial portfolio. Our bioasset products reported $26,100,000,000 in net product sales for the Q1. This is consistent with our expectations of single digit organic growth in 2023. For Thiola, We reported $21,200,000 in net product sales in the Q1, which is comparable to the same period last year. We continue to be reaching patients despite the competitive market dynamics. Speaker 400:20:19Summarizing, We are really pleased with the commercial performance to start the year. Most importantly, the initial adoption of FilSpire is progressing well and in line with our expectations. We expect the Q2 to work through the stocking from the initial launch And then we look forward to the true launch trajectory becoming more visible beginning in the 3rd 4th quarters. Let me now turn the call over to Chris for the financial update. Chris? Speaker 500:20:49Thank you, Peter, and good afternoon, everyone. Our Q1 performance was highlighted by continued strong execution across the organization as well as the strengthening of our financial position. For the Q1 of 2023, net product sales were $50,300,000 compared to $46,400,000 in the same period in 2022. The increase is primarily attributable to the 1st reported sales of FOSPARI and growth in sales of the bile acid portfolio. As for FOSPARI, we utilize the sell in methodology We recognize revenue when products are delivered to our small network of specialty pharmacies. Speaker 500:21:20As you heard from Peter, that has resulted in a large amount of the Filspari sales recognized this quarter being related to stocking in anticipation of demand. For the legacy products, as we've seen in previous years, gross to net discounts in the Q1 were higher as a result of insurance coverage changes in the beginning of the year. As we move through the balance of the year, we expect these to normalize, but they will continue to be higher for the Thiola business than in previous years. During the quarter, we also recognized $6,700,000 of license and collaboration revenue. This compares to $2,000,000 in the same period last year. Speaker 500:21:50The increase is primarily driven by a sale of drug product to our partner CSLV4 as they prepare for a potential launch of Vilspari in Europe. This activity also resulted in a nearly proportional increase in cost of goods sold for the quarter. Research and development expenses for the Q1 of 2023 were $9,900,000 compared to $56,600,000 for the same period in 2022. The difference is largely attributable to the continued advancement of our sparsentan and pactivatinase clinical programs, including clinical trial expenses, manufacturing and increased headcount. On a non GAAP adjusted basis, R and D expenses were $53,000,000 for the Q1 of 2023 compared to $53,200,000 for the same period in 2022. Speaker 500:22:30Selling, general and administrative expenses for the Q1 of 2023 $72,200,000 compared to $46,800,000 for the same period in 2022. The difference is largely attributable to the onboarding of the Sospari field team and supporting staff as well as launch related activities, including the initiation of our REMS program in patient services with the approval of the TILSPARRI launch in the Q1. During the quarter, we also began to amortize the $23,000,000 milestone payment paid to Ligand upon approval of VOSPARI. On a non GAAP adjusted basis, SG and A expenses were $55,800,000 for the Q1 of 2023 compared to $35,000,000 for the same period in 2022. Total other income net for the Q1 of 2023 was $800,000 compared to total other expense net of $9,800,000 in the same period of 2022. Speaker 500:23:17The difference is largely attributable to a recognized loss on extinguishment of debt relating to the refinancing of our convertible notes in March of 2022, partially offset by an increase in interest income. Net loss for the Q1 of 2023 was $86,300,000 or $1.27 per basic share compared to a net loss of $76,000,000 or $1.20 per basic share for the same period in 2022. On a non GAAP adjusted basis, net loss for the Q1 of 2023 was $56,200,000 or $0.82 per basic share compared to a net loss of $51,600,000 or $0.82 per basic share for the same period in 2022. As of March 31, 2023, the company had cash, equivalents and marketable securities of $561,500,000 which includes $216,000,000 in net proceeds from our underwritten offering of common equity in early March And also reflects the $23,000,000 milestone payment we made to Ligand as a result of the TILSPAR approval in February. Looking to the balance of 2023, we anticipate that our operating expenses will increase moderately and may be variable quarter to quarter as we advance our programs. Speaker 500:24:23Importantly, we will be focusing our investments in the FOSPARI launch in IGAN and the advancement of pecdevatinase as the potential first disease modifying therapy for HCU. We remain disciplined in our investment in FSGS while we work towards further regulatory guidance later this year. With our strong financial foundation, we anticipate that our balance can support our operations into 2025. This takes into account the investments I just highlighted in Telspari and pectabatinase as well as potential further competitive dynamics for Thiola and potential milestone payments related to achievements for the programs. I'll now turn the call back over to Eric for his closing comments. Speaker 500:24:55Eric? Speaker 200:24:57Thank you, Chris. We began the New Year with the 1st FDA approval from our rare disease pipeline. The accelerated approval of Vilspari marks the 1st and only non immunosuppressive treatment indicated for the reduction of proteinuria in patients with IgAN And I am very pleased with the execution so far in the launch. Most importantly, following the 1st 6 weeks of launch, We are well in line with our expectations for demand, patient access and reimbursement. And I am very pleased with how our team is executing on our launch plan. Speaker 200:25:30We will remain focused on building momentum as interest amongst nephrologists continues to grow And we look forward to providing regular quarterly updates on the Filspari launch. We also have a number of exciting milestones ahead of us this year. We look forward to the top line results from the PROTECT study in the Q4 of this year and remain highly confident in the final results achieving a statistically significant treatment effect on eGFR. As we know physicians are excited to see those data. We believe positive results will lead to traditional approval of And catalyze the next phase of growth. Speaker 200:26:05Furthermore, we are pleased with the ongoing EMA regulatory review and look forward to a potential approval of And finally, we are very excited about the opportunity in HCU. The HCU community has been highly underserved and they are eagerly seeking effective treatment options. Pegdebatinase has the Now, let me turn the call back over to Naomi for Q and A. Naomi? Speaker 100:26:41Thanks, Derek. Operator, can we now open the line for Q and A? Operator00:27:04We will take the first question from the line of Maury Raycroft from Jefferies. Maury, your line is now open. Speaker 600:27:13Hi, congrats on the progress of the launch and thanks for taking my questions. Based on The Lancet paper, PROTECT is powered at 90% to detect an underlying treatment effect of 2.9 ml per minute per year. So that translates to 5.8 ml per minute over Can you clarify if that is the delta versus irbesartan or is that only the sparsentan treatment effect? Speaker 200:27:40Maury, thanks for the question. I will turn that over to Chulo. Speaker 300:27:44Thanks Maury for the question. So to clarify, we have greater than 90 giving us a geometric mean ratio of 0.59. So when you put that on the anchor curve, it predicts a slope difference Close to what we originally modeled and it shows a very high positive predictive probability for a difference in eGFR slope Even with a modest size trial and I'll point you if you want more details, I'll point you to the anchor appendix so that you can actually do some of this analysis yourself. Speaker 600:28:32Got it. That's helpful clarification. And based on the new DUPLEX data And the view that IGAN is a progressive disease, is there anything additional you can point us to for how we should think about irbesartan ARM treatment effect size on EGFR in PROTECT. Speaker 300:28:52Well, remember the ervastartan ARM in PROTECT was already essentially optimized On RAS inhibition, they were at least 50% label, maxillary tolerated RAS. So essentially, they were treatment failures because they had persistent proteinuria despite this. And there was still an incremental reduction in proteinuria on those on Erb, but we had a 41% relative reduction in proteinuria compared to the erbasartan arm. So I would imagine that we can anticipate those on erbasartan to progress similar to what we've seen in other Studies may be slightly better and in the Tarpeo study they progressed at 6 ml per minute per year. Maybe they'll do Slightly better than that just because we had a slight reduction in proteinuria, but that is what I would say compared to the historical control. Speaker 600:29:41Got it. That makes sense. And maybe last quick question. Similar to DUPLEX, I'm wondering, do you have any feedback from FDA on whether it would be okay if you miss on total slope, but hit stat sig on chronic slope Speaker 200:29:59for Protect. Bill, why don't you take that question? Speaker 700:30:03So we don't have a specific dialogue from the See addressing that with PROTECT, in the discussions around the design of the DUPLEX study, they did say that in the end, While the study is designed around total slope first and chronic second, they certainly want to look at all the elements of the study. And I think that my expectation is they'd be consistent with each program, with that type of approach. Speaker 600:30:34Got it. Okay. Thanks for taking my questions. Speaker 200:30:37Thank you, Maury. Operator00:30:41We will take the next question from the line of Greg Harrison from Bank of America. Greg, your line is now open. Speaker 800:30:49Hey, good afternoon. Congrats on the FOSPARI number and thanks for taking the questions. Are you able to give any additional color on What part of the $3,000,000 sales number was patient demand and maybe how many patients are on treatment? And then What portion of the 146 patient start forms have transitioned into paying patients? Or At least maybe what should we expect that rate to be over time? Speaker 200:31:21Greg, thank you for the questions. We Would be in a position to be able to share as we mentioned at the approval to be able to talk about the Patient start forms as well as revenue, but we recognize certainly that early on in any phase of launch for specialty medicine, you're going to have Variability in terms of the stocking as well as how quickly you get that through. And I think as both Peter and Chris mentioned, it is going to take some time to have that while we did have some reorders or orders that reflect Underlying demand, you can largely think about that $3,000,000 as channel stocking for the Q1. And we are not going to be providing any specifics at this point with regard to the breakdown of or Conversion of Patient Start forms to reimbursement. They're very in line with our expectations. Speaker 200:32:21We're really pleased with all aspects of the launch so far. But those metrics really are lumpy in the first part of a launch and we want to make sure that we can provide a consistent set of metrics over time that are going to be predictable And consistent, throughout the launch. So stay tuned. We may evolve and being able to share some of that as we have an underlying trend emerge in the launch. But at this point, I would say that you should rely on the 146 reflecting the underlying demand from nephrologists. Speaker 800:32:50Okay. Fair enough. And then the $146,000,000 number, it's pretty impressive. I think it's above most Do you think that reflects at all a bolus of patients that was maybe waiting for treatment? Or do you expect more of a steady ramp throughout from here? Speaker 200:33:15Peter, why don't you take that one? Speaker 400:33:18Yes. Happy to do that Eric and thanks Greg for that question. Yes, you don't really see a bolus You have to realize IgA nephropathy is still a rare disease. Even though every nephrologist has at least a handful of IgA nephropathy patients, It's not like a physician has top of mind like, hey, all those patients should come in at a certain day. So I have to say, especially after spending some time in the field and seeing How busy those community practices are? Speaker 400:33:45IGA nephropathy for us is top of mind. But for nephropathy in all those patients they're serving, It's only a small, small threshold. So I don't think there's a bolus. We're happy with the steady demand that we're seeing and there's a building demand as well. But I wouldn't say there's a bolus of patients that you see initially. Speaker 400:34:03I think you will see a constant steady growing demand With regards to IGA and Pharmacy as patients are coming into the office as we progress in the launch. Speaker 800:34:15Okay, great. Thanks for taking the question. Speaker 200:34:18Thank you, Greg. Operator00:34:21We will take the next question from the line of Joseph Schwartz from SVB Securities. Joseph, your line is now open. Speaker 900:34:30Hi, thanks so much. I was wondering if you can give us any insight into how many physicians have written a filsparate prescription to date And if you can describe the earliest adopters for us? Speaker 200:34:43Peter, why don't you take that question? Speaker 400:34:48Yes. At this point, to your earlier point, we won't be disclosing like how many prescribers we have. We have seen Repeat prescriptions already. I think it's in line with what you may have expected given the 140 6 patient thought forms. We're very pleased with the way physicians are Receiving the product right now. Speaker 400:35:13And to your point, like what is the profile of the prescriber so far? Well, we have really been targeting based on 3 aspects. 1 is volume, patient volume in the clinic as well as the physicians' behavior in adaptation of new Innovation as well as the influence. And we see that especially the patients, the physicians And lost community practices are key to prescribed so far. Okay. Speaker 900:35:43Thank you. And then, maybe a question on your HCU program. We hear that these patients can be somewhat elusive. So I was wondering if you can describe Your relationship with the patient community and the physicians that treat them and how has that evolved since running the COMPOSE study? How challenging was that to enroll? Speaker 900:36:04And do you think how much of a challenge do you think it could be to enroll a larger Phase 3 study? Speaker 200:36:12Yes, Joe, thank you for the great question. I'll start by sharing a little bit about the relationship and how the community has evolved. And then I'll ask Jula to share Some of the insights that her team has gathered in conducting the COMPOSE study. This is a patient community that really has been underserved. And when we took over the program, many of them were actually served by connecting with phenylketonuria or PKU community because of a lot of the similarities and how the conditions are managed. Speaker 200:36:44But I think as we've started to really build our relationship with them, They really start to build their own community online as well as with kind of the standard patient advocacy organizations, Both here in the U. S. As well as abroad. And I think that we're starting to see a much more concerted and organized effort to articulate what the needs of that community are with regard to earlier diagnosis, improving newborn screening, Helping to understand better management of the disease as well as I think for us educating about the importance of engaging in the clinical trials as a So I think largely we've been really pleased with how quickly the community has evolved And I think we've really gained a lot of good learnings with regard to clinical trial enrollment. And with that, I'll turn it over to Jula Speaker 300:37:41Thanks, Eric. Well, any rare disease, it can be challenging to recruit because there's very few patients So it can take a bit longer and you often have to go to where the patients are and you really do need to engage with your advocacy partners and with the patient community to understand what's important to them, simplify the trial design and provide them a lot of support. And so that's what we're doing moving forward. I would say also importantly, We have significant engagement with the key opinion leaders to make sure that what's important to them and their patient community is what we incorporate into the design of the study. And then we also have a natural history study that helps us with having access to patients who if they're Speaker 400:38:33Thank you for the insights. Speaker 200:38:36Thanks, Joe. Operator00:38:39We will take the next question from the line of Carter Gould from Barclays. Carter, your line is now open. Speaker 1000:38:46Hey, this is Leon Wang on for Carter. Thanks for taking my question and congrats on the results. So, on Fospari, any early signs of the patient profile that docs are prioritizing versus those that they may be waiting for more confirmatory EGFR data or any profiles of docs that may be Perhaps waiting for data and not as receptive to the initial launch. Speaker 200:39:18Yes. Thanks for the great question. Maybe I'll start by saying with any launch, you typically will see A spectrum of adoption by physicians where you have some that are early adopters and those that are waiting. That so it's not surprising that there will be some physicians that want to wait. What I will say is that we're very pleased and the performance thus far from physicians is Absolutely in line with our expectations and also in my experience with launches. Speaker 200:39:48I'll ask Peter to share a little bit more about the types of patients that we're Seeing prescribed FOSFARI in the 1st 6 weeks as well as the profile physicians that we see adopting. Speaker 400:40:00Yes. Thanks, Eric. Happy to provide some color on the patients that we are seeing. So the majority, the vast majority of the patients Those patients that are on rapid path of progressing with consistent hypoximuria levels. Many of those Are above 1.5, but we also have some prescriptions for patients with lower proteinuria levels than 1.5, but have additional indicators for rapid progression. Speaker 400:40:26So I think largely in line with how the indication is written, nearly above 1.5 with some also below 1.5 gram per gram. Speaker 200:40:38Maybe the other thing that I'll Peter that I'll add is That the payer mix is very consistent with what we had assumed with the majority of these patients having commercial insurance. So I think A lot of the work that Peter's team did to really profile what this look like, what the launch update could look like It's again very much in line with our expectations and planning. Speaker 1000:41:04Great. Thank you. Speaker 200:41:06Thank you. Operator00:41:10We will take the next question from the line of Sabayko from Evercore ISI. Lisa, your line is now open. Speaker 100:41:19Hi, there. Thanks for taking my call Speaker 1100:41:21and congratulations on The initial good start here. What just I know you wouldn't have this right now, but as we think about sort of Later in the year, what kind of gross to net can we expect? What would it be initially? And I'm not saying about this quarter, but And then what do you think it will stabilize around? Speaker 200:41:43Yes, great question, Lisa. Certainly, as you alluded to, the first part of a launch It's going to be quite lumpy. So we've been reluctant to provide any estimates at this point, but I'll ask Chris to comment on where we think we may be landing once we get to that It's a steady state. Speaker 500:42:01Yes. Thanks for the question, Lisa. Really at stable state, we're going to be looking at mid to high teens. And I think what we're seeing now is reflective of us getting there once we do get to that stable state. So no change from our expectations on that point. Speaker 1100:42:17Okay. And then just back to the Protecta and your powering. So Jula, can you just clarify? So you saw a 2.9 so you're powered for a 2.9 Milliliter difference with slope, that was assuming 30% difference in proteinuria, but you actually got a bigger delta than that. So now You should have a greater difference. Speaker 1100:42:44Is that the right way to think about that? Can you just I didn't hear everything you said. It was a little confusing. Speaker 200:42:50Yes. Julie, would you like to take that? Speaker 300:42:54Well, our initial power calculation was based on historical data. And then you can map it based on the anchor data. So based on the anchor data, we fall in line with our original Power calculations to be able to predict a statistically significant and clinically meaningful effect at 2 years. The other thing I do want to add to this is that as part of our review for accelerated approval, the FDA was very focused That we would be able to confirm our benefit at the 2 years. So they asked us the likelihood of Achieving statistical significance both on the chronic and total slope endpoints for the 2 years. Speaker 300:43:34So we provided conditional power calculations that looked at our available eGFR data at the time of the interim as well as the information from the trial level analysis to address their request. And importantly, the conditional power calculations provide a very high level of confidence on achieving statistical significance at the 2 year confirmatory analysis. Speaker 100:43:57Okay. Thanks. Speaker 200:43:59Thanks, Lisa. Operator00:44:03We will take the next question from the line of Mohit Bansal from Wells Fargo. Mohit, your line is now open. Speaker 900:44:11Thanks for taking our questions. This is Speaker 800:44:12Adam on for Mohit. Speaker 900:44:14Could you discuss whether you think naive patients or patients switching to Filspari Is the bigger driver of demand in the 1st year of the launch? And then separately on the 3% of insured lives being covered, Is that ahead of your expectations? And how could we think about that going from here, the type of cadence from quarter to quarter? Speaker 200:44:36Sure. Peter, why don't you take those two questions? Speaker 400:44:43Yes. Hi, Peter Erik. Thanks for that question. So when you think about like where is the main demand coming from with regards to Speaker 800:44:51patients naive or switched, it is Speaker 400:44:51very consistent like the It is very consistent like the majority, the vast majority of those patients have been on ACE or ARBs in the past and are switched So I think that is quite consistent. I think ultimately you will start to see naive patients as well. I think It's a small fraction of the total patient population because the majority of those patients are prevalent already in the offices of the physician. So what we are seeing right now is much of that phenomenon, patients that have not been managed to the proteinuria levels at the physician once And ACE or ORCs are being replaced with skilled flowery. So that was the first part of your question. Speaker 400:45:35With regards to the 2nd part of the 38% coverage, it's a good number and it's not in line with Expectation, especially if you take into consideration that it was only after 6 weeks. So 38% coverage by March 31. I think it's a good number that we feel quite proud of and I think it's at the high end what you see with Benchmark products. Speaker 200:46:00Yes, Adam, thank you for that Peter. The only thing I would add with regard to actually both of those questions is the quality of the Payer coverage, it's really important to think not just about coverage, what's the quality of the coverage relative to the labeled indication and we're really pleased to see There's a high degree of quality when we think about the access for patients aligned to the label. And we do see a number of those payers that have stepped through ACE or ARB. But again, as Peter alluded to, the majority of these patients are already on ACE or ARB. In fact, many of these patients are referred to their nephrologists on ACER ARB. Speaker 200:46:40So when we look at the actual quality of the coverage, it's not just the 38%, but it's actually the quality of that access and we're really pleased. Again, early days, but I think it's a great foundation upon which to build throughout the rest of this year. Operator00:47:04Any further questions, sir? We will take the next question from the line of Laura Chico from Wedbush Securities. Laura, your line is now open. Speaker 100:47:18Thanks very much. I guess I wanted to talk a little bit more about the cadence of Ordering here. And I guess Eric maybe said differently, could you just walk us through what are the expectations around the timing From receipt of a start form to when product is actually going to be dispensed, like what is the timeframe there? Sorry if I missed it. Speaker 200:47:42Yes. No, it's a great question, Laura. And it's an important dynamic to think about any specialty launch, where there is a range of timelines for from prescribing. And I'll ask Peter to talk a little bit about what we're seeing and also what we Expect to see throughout the rest of this year. Peter? Speaker 400:48:05Yes. I'm happy to respond to that. Thanks, Laura, for that question. I think to Eric's point, as is typical for many rare disease product launches, there's a wide range of what I call the time to fulfillment, especially in the early days as payer access may take longer. Some would say in these early days, the sales party time to We anticipate that this pull through will decrease as we get more payer coverage. Speaker 100:48:42And I'm sorry, Peter, just to verify, you said it's ranging from 20 to 60, but over time would likely to be closer to a typical 30 day range. Do I have that correct? Speaker 400:48:51Well, let me clarify that, Laura. I was talking about what is common in rare disease in general, but I would say, we are in that range. It's more historically what I've seen in rare disease and specialty launches. So this is not reflected on shelf Speaker 200:49:09Understood. Yes. I think the important aspect, Laura, to keep in mind is the we won't provide any specific numbers because it really is only the 1st 6 weeks of experience after approval, what's important is as we get more broader coverage and high quality coverage, That lead time should shrink. And I think what's important in the experience that Peter's team has had is that we've already one, we're Off to a great start with regard to payer coverage and reimbursement, but we're already starting to see that average time to fill Reduce. And I think that as Peter's team continues to execute and we continue to get growing coverage, We'll continue to see that average time as well as the range reduced. Speaker 200:49:57So again, really early days, so we don't want to give numbers because it is lumpy. But the dynamics that we're seeing are exactly what you would expect to see with this successful launch. Speaker 100:50:08Okay. That's helpful. And maybe I'll Speaker 400:50:10sneak in one quick follow-up Speaker 100:50:11And again, apologies if I missed this, but did you quantify yet how many physicians have signed up for the REMS at this point? Speaker 200:50:20Peter? Speaker 400:50:22Yes. No, we haven't given a number there, but we're very pleased as with the patient's platform. So we see Steadily increase in ramp certifications and enrollment. And I think it speaks to the physicians that they understand The value that COSPARI may have for their patients, but also that I understand that the REMS Operator00:50:53We will take the next question from the line of Tim Lugo from William Blair. Tim, your line is now open. Speaker 1200:51:01Hey, guys. This is Lachlan on for Tim. Thanks for taking the questions. So I guess heading into the launch, one of the headwinds you guys had mentioned Well, potential headwinds was just that physicians wouldn't really have wouldn't know the data very well because it's obviously not much had been released. So I'm just wondering how much I guess, how that has played into the launch so far? Speaker 1200:51:24Have you seen That sort of affecting any of the interactions or the speed at which physicians are maybe starting to prescribe? Or is that really Not affecting that rate, I guess, compared to what you expected. Speaker 200:51:41Yes. It's a great question, Lachlan. I think First, I'll point to what Jula mentioned in having a high profile publication Of the interim data that I think really gives physicians a better understanding about the data. But Peter, why don't you share a little bit more about what Hearing from your team about going through the data on Gylfari. Speaker 400:52:07Yes. Happy to do so. So indeed, nephrology in general is not as much inclined with innovation as maybe some other specialists, Given that there has been so little innovation to nephrology in general. And I think that's a phenomenon that we have seen with other Neufrology launches, in particular rare launches. To Eric's point, I think having new data and this is kind of like a rolling launch because we launched In the 1st 6 weeks without having a publication or without having further data, which is not very common to launch a product without that specific. Speaker 400:52:43So we lost basically on the PI also given the promotional restrictions in the Software AG's products with Brazilian accelerated approval. But now that we have the lens of publication and you start to improve you in Medellin guidance like UpToDate and As Joanna mentioned in her part of the prepared remarks, I think that further provides confidence and provides more insights in that process as well. So I think we I'm very pleased what I'm seeing, both on the intent to prescribe, but also on the actual prescriptions already, and that's the 146 patients for the river in Lolito. I think as we get more data and we have those publications, this will continue to have Bring confidence to the Pharosy community and allow for continued and accelerated scripts. Speaker 200:53:35Yes. I think that's absolutely right, Peter. And I Share with you, 2 maybe additional observations. And like Peter, I spent quite a bit of time in the field Meeting with customers, I think there's a real eagerness to understand the profile and the data of Filzpari more. So the Publication and guidelines are going to really help provide some of that independent or third party perspective. Speaker 200:54:03But the other aspect is that it really helps understand the REMS better and the profile of A low rate of ALT, AST elevation because I think in the absence of that information, it was hard for physicians to put into perspective what the Full of risk really is and I think it's been very reassuring for physicians when they see the actual rates in the publication and in the label. Speaker 1200:54:32Got it. Thanks. And on the topic of reimbursement, I think you mentioned that most of it had gone through, but there were some delays for the patients that you're seeking reimbursement for. I guess to the extent that there have been delays, Can you maybe talk about what pushback you're getting from payers? Speaker 400:54:54No, I wouldn't say it. I mean, as you don't have inclusion in the formulary yet, I mean, it goes through the prior authorization pathway. So that generally takes a lot. I mean, I think that's a common process in rare diseases in particular. So I wouldn't indicate this as like particular obstacles that we are seeing for Phil Starry. Speaker 1200:55:18Got it. Thanks. Speaker 200:55:20Thanks, Auchlin. Speaker 100:55:23We will Operator00:55:24take the next Question from the line of Vamil Divan from Guggenheim Securities. Vamil, your line is now open. Speaker 1300:55:32Great. Thanks for taking the questions. I think most of mine on the launch have been answered, but I just or asked and answered. But just one more, just in terms of the patients that are getting So far, obviously, it is early. I'm trying to get a sense that you mentioned sort of the ASINR dynamic. Speaker 1300:55:48But in terms of SGLT 2, if you can comment on narvelesside patients already on SGLT2s or not? And also curious with the label mentioning the greater than Particle 1.5 gram per gram, is that sort of metric that physicians seem to be sticking with? Or are they just using their judgment and maybe And then the second question is more on the expense side, I guess, for Chris. Just How we should think about, especially SG and A, the spin this quarter, Q1 was a little bit more than we were expecting. Is this sort of A reasonable amount to assume going forward or is there still a little bit of buildup, we should expect sort of higher ramp up as we get into 2Q and 3Q this year. Speaker 1300:56:32Thanks. Speaker 200:56:34All right, Pavel. Thanks for the questions. Peter, why don't you take the first on the patients? Speaker 400:56:41Yes, it's a good question. Maybe I'll start answering the question by giving a broader perspective on the patient profile Because this is often a younger patient population, right? Many of those patients are being diagnosed in the late teens, early 20s. And that's what we are seeing as well, many young patients that are on a path of rapid progression. And to your point, Right. Speaker 400:57:02What we're seeing is many of the current available medication doesn't bring patients to the level to the target level that physicians would like to see. Jason, Arps didn't do that. We have SGLT2. I think that's something that you mentioned as well, and we see that increased utilization in SGLT2. The physicians feel very comfortable in combining if needed or if appropriate with SGLT2 as It's mechanistically synergistic, but also sales firing has that very rapid progression of 50% First, I know we are rushing that physicians haven't seen risk other medication, especially the non immunosuppressive nature of chilSpari With or without combination with SGLT2 makes physicians very comfortable, especially when you talk about the younger patient profile That have been yes, the side effect profile of immune suppression is not very pleasant, especially for this patient population. Speaker 200:58:04And Chris for expenses. Speaker 500:58:06Yes, absolutely. Thanks for the question, Vamil. What I would point back to is in the prepared remarks Talked about for overall expenses, we anticipate moderate increases for the balance of the year. And really when I think about the breakdown of SG and A and R and D, That's probably more pointed towards R and D as we look to continue both the DUPLEX and PROTECT studies that are going to continue on for the balance of the year, But then also the pegmatinase work that's going to go into the potential initiation of a Phase 3 as well as the supply CMC work that all needs to be done to Scale up for both Phase 3 and commercial. And so I think that's where you'll see likely the larger magnitude of increase come for the year. Speaker 500:58:43I think from an SG and A perspective, There may be some modest increase from this point, but I wouldn't expect it to be of any significant magnitude. And really what we've gotten to And this Q1 is the first time in which you've had the full sales force fully in place, doing all the promotional activity and Putting that right investment behind Filspari to make sure we can position it appropriately for IGA. Speaker 1300:59:09Okay, great. Thank you. Speaker 200:59:12Thank you. Speaker 100:59:14We will Operator00:59:15take the next question from the line of Alex Thompson from Stifel. Alex, your line is now open. Speaker 1400:59:22Hey, great. Thanks for taking my questions. I got one iYan question and one FSGS question. I guess on iYan, I'll try to ask another sort of commercial dynamics question. I guess given that you're starting by targeting a lot of higher volume prescribers, Speaker 400:59:35can you talk a Speaker 1400:59:36little bit qualitatively about whether A majority of the start forms that you're seeing so far coming from single physicians or multiple physicians writing Multiple start forms for patients or is it broader than that? And then on FSGS, can you comment on sort of In rare disease especially. Thanks. Speaker 201:00:06All right, Alex. Thanks for the questions. Peter, would you like to take the IGAN question? Speaker 401:00:13Yes. Thanks, Alex. So if I understand your question correctly, your question was like do you see mainly Prescription from prescribers that have multiple prescriptions or more single and if it's mainly in the higher volume centers. Speaker 1401:00:30I think it's too Speaker 401:00:31early to make a specific statement on that. I think we see The majority of the prescriptions coming from community centers, especially from larger community centers, but we also see prescription from academic centers. And we see a mix of Physicians that have prescribed a single time or a second time. So but again, it's early days. I'm prescribing this I'm describing this for the 1st 6 weeks, so I wouldn't be too much into it. Speaker 401:00:58We see a large prescriber base and we see both single as well as multiple prescriptions Speaker 201:01:08And Bill, why don't you take the question on regulatory flexibility? Speaker 701:01:14Yes. No, happy to. I think the one that comes to mind quickest is Entresto for congestive heart failure It was approved by Cardio Renal, I think in 2021, if my memory is right. And that was a drug that missed their primary endpoint, but the decision in the Agency was that there was clear benefit and across the trial based on totality of evidence and unmet need That was something that they were interested in approving. I think that there have been other instances across Rare disease indications and I think the most recent work that I read was in JAMA where they said in about the past 5 or 10 years, about 10% of the drugs approved by the FDA were ones that missed their primary endpoint In their pivotal studies. Speaker 701:02:06So it's not the norm, but it's also not something that's unheard of. Speaker 201:02:12And, Julie, anything further that you'd like to add on that question? Speaker 301:02:18I would also point to Fabry It's another potential indication for megalinostat to look at as another reference. Speaker 1401:02:28Great, helpful. Thanks so much. Speaker 201:02:31Thank you. Operator01:02:34We will take the next Question from the line of Ed Arce from H. C. Wainwright. Ed, your line is now open. Speaker 1501:02:41Great. Thanks for squeezing me in here and Congratulations on the early progress on the launch. I see here, obviously, 1st 6 weeks, $3,000,000 is, as you said, represents mostly stocking and 146 PSFs, mostly demand. And I recognize as you pointed out that it's highly variable at the beginning. But I'm wondering as we get through the next few quarters And Nir, if there are specific launch metrics that you intend to report regularly, for example, we've already discussed Sort of the fulfillment conversion rate or number of prescriptions or patients on drugs and then perhaps later Numbers around persistence or compliance rate. Speaker 1501:03:34And just so that's first. And then secondly, just wanted to ask as well on The readout later this quarter in HCU with the higher dose and the lyophilized formulation. The focus clearly is at least partly on the efficacy look From that dose as well as the PK with the new formulation, but what other aspects to the data readout Could we expect later this quarter? Thanks so much. Speaker 201:04:09Yes. Thanks Ed for the great questions. I'll take the first one. So I think we certainly can are looking at a number of different metrics. And it's important for us to make sure that the metrics that we provide regularly are ones that we have confidence in the sort of trendability and the predictability. Speaker 201:04:28We believe that's why we've focused on patient start forms and access because they really are robust predictors of underlying demand as well as the ability to pull through and have those reimbursed. I think as we look forward, you can imagine that there may there likely will be others like The persistence rates or the reimbursement rate and you can look to our commercial business where we have talked about Persistence, the high rate of persistence, etcetera. So as we start to understand the underlying dynamics of the Filsparin launch, We'll look to evolve what those are. But again, we want to make sure that we really focus on those fundamentals this year that we believe are going to be most important in the 1st year of launch. And then with regard to the readout of the Cohort 6 in the COMPOSE study, Bill, I'll turn to you to provide some further perspective on what we'll be looking for and possibly what we would be Disclosing, but I will say we haven't yet committed to what we will disclose specifically. Speaker 201:05:36Bill? Speaker 701:05:38Sure. The Cohort 6, we utilized the highest dose to date on a mg per kg basis In the study, in what we view as the final cohort in the COMPOSE study, it also gave us the opportunity to utilize the lyophilized Formulation and evaluate that in patients. What we're looking for is the most predominant biomarker It's going to be the reduction in homocystinuria or in total homocystine over time in the 12 week double blind portion of COMPOSE. In addition to that, of course, we're looking at safety and tolerability. It's a Phase onetwo study and evaluating that for those Individuals at that dose and those patients will roll over into the open label Speaker 401:06:27extension Speaker 701:06:28that will give us the data then to select a dose and help us with the design of the Phase 3 study. Speaker 1501:06:38Sounds good. Thank you so much. Speaker 901:06:40Thank you. Operator01:06:43There are no further questions at At this time, Ms. Eichenbaum, I will turn the conference back over to you for any additional or Speaker 401:06:51closing remarks.

The Q1 of 2023 has been one of critical milestones representing significant progress across the organization. These advancements have positioned Travir for sustained growth led by the ongoing launch of FilSparri in IgA nephropathy and bolstered by the continued progression of our pipeline. The most notable achievements in the quarter was the U. Speaker 200:02:09S. Accelerated approval of FilSpari or sparsentan for the reduction of proteinuria in adults with primary IgA nephropathy or IgAN at risk of rapid disease progression. The approval of TILSPARI marks the 1st and only non immunosuppressive therapy for the reduction of protein proteinuria in IgAN. While we are only in the early stages, the commercial launch is progressing very well and in line with our expectations. Today, we'll focus on the important takeaways from the 1st 6 weeks, but I am very pleased with the early demand and the commercial organization's execution, which instills confidence that we will effectively position TILSPARI to meet or exceed our internal goals for the year. Speaker 200:02:55Furthermore, we were very excited to see the interim results from the PROTECT study published in The Lancet. These data further elucidate the to the active control herbosartan. The compelling data sets support our confidence in a positive outcome from the 2 year secondary endpoints in the Q4 of this year. Overall, it was a great quarter for our efforts to establish the foundation for to become a new treatment standard in IgAN for the addressable population. Earlier this week, we were disappointed to report that our Phase 3 DUPLEX study of sparsentan and FSGS did not achieve the primary efficacy EGFR endpoints. Speaker 200:03:47FSGS is a very difficult disease to study. Despite this, sparsentan still managed to demonstrate a consistent profile characterized by sustained proteinuria reduction and a well tolerated safety profile over 2 years. We will continue to analyze the datasets and engage with the FDA and EMA to explore the With regard to pegmatinase, we continue to be highly encouraged by the forward momentum in our program for classical homocystinuria or HCU. As many of you will recall, HCU is a serious and progressive metabolic disorder that can lead to thrombotic events, Serious vision problems due to lens dislocations, bone malformation and a constellation of mental and psychiatric complications. Importantly, pegdevatinase is well positioned to potentially become the 1st and only disease modifying approach to treat HCU. Speaker 200:04:52We have made recent strides in our program and remain on track to report data from Cohort 6 in the 2nd quarter. We are incredibly grateful to the patients, family members and physicians who have supported us in our pursuit of therapeutic advancements for diseases Our team remains committed to our mission of improving the lives of those living with rare disease, delivering for our patients for the rare disease community and our shareholders. Now let me turn the call over to Jula for a clinical update. Jula? Speaker 300:05:28Thank you, Eric, and good afternoon, everyone. I'll start by highlighting our continued efforts to support the awareness and Education of the Filspari clinical profile. As Eric mentioned earlier, we were very pleased with the recent publication of the interim results from the Phase 3 PROTECT study in The Lancet. The rapid publication in this renowned journal speaks to the scientific relevance and strength of the PROTECT interim results in IgA nephropathy. The publication serves as a great platform to showcase the interim results from PROTECT, The largest interventional study of its kind in IgA nephropathy. Speaker 300:06:09The published results detail the rapid and sustained reductions of proteinuria Weeks of treatment in PROTECT. A significantly greater proportion of patients on FilSpari achieved complete and partial remission of proteinuria. As recently published, most high risk IgAN patients will face kidney failure within their lifetime, And reducing and maintaining lower thresholds of proteinuria, particularly to levels less than 0.5 grams per day can impact long term kidney outcomes. We also saw encouraging early trends on important kidney outcomes. Here approximately half the number of patients treated with VILSPARI reached the confirmed 40% reduction in eGFR from baseline, Kidney failure or all cause mortality compared to irvastatin. Speaker 300:07:14Furthermore, important data were included that support our belief And the primary efficacy objective of the Phase 3 PROTECT study that optimally antagonizing Endothelin 1 and angiotensin 2 with sparsentan may lead to protective effects in the kidney structure and function beyond hemodynamics. Specifically, the authors drew the conclusion that the proteinuria lowering effect of sparsentan is unlikely to be attributable to differences in blood pressure, especially given the large differences in proteinuria reduction relative to minimal differences in blood pressure. Finally, The publication also included additional safety data from the interim analysis, which reported no cases of heart failure at the time of the analysis, No treatment discontinuations or serious adverse events of peripheral edema and no significant difference in weight change between treatment arms. These published interim results and the preliminary eGFR data from the interim analysis and the clinical literature Demonstrating the relationship between proteinuria reduction and eGFR benefit support our steadfast confidence for clinically meaningful and statistically significant treatment effect on EGFR after 2 years of treatment with sparsentan. I'm pleased to report that the PROTECT study continues to accrue patient data as expected and remains on track for the scheduled top line readout in the Q4 of this year. Speaker 300:08:45Since Filspari's accelerated approval, We've also received solid support from the nephrology community, including physicians, patients and advocacy groups. Following a discussion with an academic nephrologist at NKF, I learned that the Lancet publication was the primary reason behind their decision to We are receiving similar anecdotes that physicians intend to alter the way that they treat their patients by including VILSPARI as a key treatment option now that it's available. Importantly, VILSPARI is now included in the treatment recommendation or switching the RAS inhibitor to Filspari. We eagerly look forward to the confirmatory Phase 3 PROTECT study data, which we believe will put us in a strong position to enable Filspari to become the new foundational therapy in IgAN. Since we recently hosted an update call, I'll only briefly touch on sparsentan's development in FSGS. Speaker 300:10:03While we were disappointed to report that the DUPLEX study did not achieve statistical significance on the EGFR endpoint, It did demonstrate consistent proteinuria reduction of 50% across studies. Importantly, we also saw that with a higher dose, Since we reported our results, we've had a chance to engage with both nephrologists and the patient community. The resounding feedback has been supportive and encouraging. This combined with the positive trends seen in the study further supports our motivation in seeking a path forward with regulators in both the U. S. Speaker 300:10:39And Europe. Beyond sparsentan, we continue to advance our Pegtobatinase program in classical homocystinuria. As many of you will recall, in the first five cohorts of our ongoing Phase onetwo COMPOSE study, Tectabatinase demonstrated a dose dependent response and ability to dramatically reduce total homocysteine to clinically meaningful levels with the 1.5 milligrams per kilogram dose. Importantly, pecovatinase was able to show a generally well tolerated In the 6th cohort, we're examining a higher dose and lyophilized formulation, which will give us valuable insights for the program's next steps and aid our discussions with regulators regarding the design of a Phase 3 study to potentially initiate in the second half of this year. Additionally, we've made recent progress on our manufacturing to support a pivotal program and commercialization. Speaker 300:11:47And so we look forward to sharing an update on those data later this quarter and plan to provide an update regarding next steps for the program later this year. With that, I'll turn the call over to Peter for the commercial update. Peter? Speaker 400:12:01Thank you, Zohar. I'm pleased to report that we are making great progress in the early days of sales party launch. Our results in the Q1 included only 6 weeks, and we are in line with our expectations. We are encouraged with the strong level of interest and engagements that we are seeing across stakeholders, including patients, physicians and payers. Let me reflect on our progress and share some of the metrics that we saw in the 1st week 6 weeks of approval until the end of Q1. Speaker 400:12:32Since our approval on February 17, we have remained focused on our 3 launch priorities, educating nephrologists Have a positive first experience with Phil's diary. 1st, looking at our physician education efforts, Our commercial field team of over 80 seasoned professionals is successful in getting access to nephrologists and educating them on the sales party label. Our strategy is to ultimately reach a universe of 6,000 nephrologists, representing roughly 85 We have face to face interactions with over 2,500 of these nephrologists in the first These engagements are aligned to our profiling insights, and we are reaching those nephrologists that have been And we believe we'll be the early adopters. The reception to Falspar's efficacy and safety profile has been strong. Physicians consistently mention the impressive proteinuria reduction with Trosparin and the importance of having the non immunosuppressive IgAN therapy. Speaker 400:13:51And we are excited to see a strong increase in brand awareness now that our team is actively discussing TOSPARI with nephrologists. As mentioned on the last earnings call, we received our 1st patient start forms on the 1st working day after approval, which was also the day that we started educating physicians about XERSPARRI and the first product was shipped to the patients the week after, Just 8 working days from approval. We heard from one of these early prescribers and anecdotally, With his first patients treated with TOSFARI over the 1st 6 weeks, he has observed a rapid proteinuria reduction consistent with what was These are the stories that energize our incredibly dedicated bonds team. This team is going steadfast in serving and educating our stakeholders. And it is encouraging that we are starting to hear how patients may be benefiting from Tversary Treatment. Speaker 400:14:54In the 1st 6 weeks, Travir Total Care received 146 patient start forms, And we see an increasing number of physicians getting involved in the REMS program as they have identified patients who can benefit from full styrene. Secondly, we are making robust progress in educating payers on IgAN as the leading bone marrow disease pause for kidney failure and that most IgAN patients progress to kidney failure within 10 to 15 years of diagnosis And the meaningful the meaningfulness of proteinuria is a prognostic indicator for disease progression. Within that context, Our in field account teams emphasizing Filsparis' compelling value proposition to the payers. As a result of these educational efforts, We are seeing Fiospiri is being discussed at P&T committees. And the first formularies In the 1st 6 weeks, We achieved 38% payer coverage of the U. Speaker 400:16:10S. Population. In the coming months, we anticipate coverage will continue to expand, We will periodically share our continuing progress. Similar to other newly approved therapies for rare diseases, Initial access to Filzpari is mainly through prior authorization and if denied through appeal processes. We are encouraged with the rate that patients are able to gain access. Speaker 400:16:38Since the claim Experience a slow or delayed communication process, we have support programs to provide eligible patients with access to products. Finally, our 3rd launch priority is providing iGAM patients, their caregivers and the treating physicians with a positive experience in It was designed with the patient in mind to offer easily accessible programs, including personalized education, assistance in the REMS process, Supporting the reimbursement process and co pay assistance for eligible patients. Initial patient feedback is rewarding as we hear through TRILIA Total Care about patients' appreciation for these offered services. Turning to Tralea Total Care, we designed and launched support services to streamline and simplify the REMS enrollment and implementation process for physicians and patients. We are hearing from nephrologists that the REMS process is straightforward. Speaker 400:17:46Hence, to my earlier point, We are seeing a significant number of physicians enrolling in the REMS program because they have patients identified that could benefit from TOSPARI. From a financial perspective, we finished the Q1 with Netfield Styrene sales of $3,000,000 It is important to note that this is predominantly based on the specialty pharmacies initial starting of the distribution channel. As you may recall, we utilize a small network of specialty pharmacies to maintain high services for our patients. One of these specialty pharmacies has multiple regional distribution centers that each elected to stop for the initial launch to be ready for demand. As a result of this, we anticipate that a meaningful portion of this stocking in the Q1 will be drawn down in the 2nd quarter and impact our Q2 revenue. Speaker 400:18:41We anticipate that it will begin to that we will begin to see a more representative trajectory of both demand and reimbursement in the Q3 and a clear view by the Q4. Overall, I believe that the launch is off to a strong start. We are seeing steady demand building. The initial metrics that I shared indicate the nephrology community's excitement of the Aspirus potential for IgAN patients. With the recent plans and publication of the PROTECT interim analysis, inclusion of Filspiri in the treatment guidance tool up to date, The personal experience that nephrologists are getting on the rapid and sustained proteinuria reduction with TILSTARI in their own patients And the number of nephrologists that are now involved in the REMS program gives me confidence that we will continue building the momentum. Speaker 400:19:37With respect to the commercial performance outside of SureSpire, I am really pleased how our team is continuing the strong execution in connection with our established commercial portfolio. Our bioasset products reported $26,100,000,000 in net product sales for the Q1. This is consistent with our expectations of single digit organic growth in 2023. For Thiola, We reported $21,200,000 in net product sales in the Q1, which is comparable to the same period last year. We continue to be reaching patients despite the competitive market dynamics. Speaker 400:20:19Summarizing, We are really pleased with the commercial performance to start the year. Most importantly, the initial adoption of FilSpire is progressing well and in line with our expectations. We expect the Q2 to work through the stocking from the initial launch And then we look forward to the true launch trajectory becoming more visible beginning in the 3rd 4th quarters. Let me now turn the call over to Chris for the financial update. Chris? Speaker 500:20:49Thank you, Peter, and good afternoon, everyone. Our Q1 performance was highlighted by continued strong execution across the organization as well as the strengthening of our financial position. For the Q1 of 2023, net product sales were $50,300,000 compared to $46,400,000 in the same period in 2022. The increase is primarily attributable to the 1st reported sales of FOSPARI and growth in sales of the bile acid portfolio. As for FOSPARI, we utilize the sell in methodology We recognize revenue when products are delivered to our small network of specialty pharmacies. Speaker 500:21:20As you heard from Peter, that has resulted in a large amount of the Filspari sales recognized this quarter being related to stocking in anticipation of demand. For the legacy products, as we've seen in previous years, gross to net discounts in the Q1 were higher as a result of insurance coverage changes in the beginning of the year. As we move through the balance of the year, we expect these to normalize, but they will continue to be higher for the Thiola business than in previous years. During the quarter, we also recognized $6,700,000 of license and collaboration revenue. This compares to $2,000,000 in the same period last year. Speaker 500:21:50The increase is primarily driven by a sale of drug product to our partner CSLV4 as they prepare for a potential launch of Vilspari in Europe. This activity also resulted in a nearly proportional increase in cost of goods sold for the quarter. Research and development expenses for the Q1 of 2023 were $9,900,000 compared to $56,600,000 for the same period in 2022. The difference is largely attributable to the continued advancement of our sparsentan and pactivatinase clinical programs, including clinical trial expenses, manufacturing and increased headcount. On a non GAAP adjusted basis, R and D expenses were $53,000,000 for the Q1 of 2023 compared to $53,200,000 for the same period in 2022. Speaker 500:22:30Selling, general and administrative expenses for the Q1 of 2023 $72,200,000 compared to $46,800,000 for the same period in 2022. The difference is largely attributable to the onboarding of the Sospari field team and supporting staff as well as launch related activities, including the initiation of our REMS program in patient services with the approval of the TILSPARRI launch in the Q1. During the quarter, we also began to amortize the $23,000,000 milestone payment paid to Ligand upon approval of VOSPARI. On a non GAAP adjusted basis, SG and A expenses were $55,800,000 for the Q1 of 2023 compared to $35,000,000 for the same period in 2022. Total other income net for the Q1 of 2023 was $800,000 compared to total other expense net of $9,800,000 in the same period of 2022. Speaker 500:23:17The difference is largely attributable to a recognized loss on extinguishment of debt relating to the refinancing of our convertible notes in March of 2022, partially offset by an increase in interest income. Net loss for the Q1 of 2023 was $86,300,000 or $1.27 per basic share compared to a net loss of $76,000,000 or $1.20 per basic share for the same period in 2022. On a non GAAP adjusted basis, net loss for the Q1 of 2023 was $56,200,000 or $0.82 per basic share compared to a net loss of $51,600,000 or $0.82 per basic share for the same period in 2022. As of March 31, 2023, the company had cash, equivalents and marketable securities of $561,500,000 which includes $216,000,000 in net proceeds from our underwritten offering of common equity in early March And also reflects the $23,000,000 milestone payment we made to Ligand as a result of the TILSPAR approval in February. Looking to the balance of 2023, we anticipate that our operating expenses will increase moderately and may be variable quarter to quarter as we advance our programs. Speaker 500:24:23Importantly, we will be focusing our investments in the FOSPARI launch in IGAN and the advancement of pecdevatinase as the potential first disease modifying therapy for HCU. We remain disciplined in our investment in FSGS while we work towards further regulatory guidance later this year. With our strong financial foundation, we anticipate that our balance can support our operations into 2025. This takes into account the investments I just highlighted in Telspari and pectabatinase as well as potential further competitive dynamics for Thiola and potential milestone payments related to achievements for the programs. I'll now turn the call back over to Eric for his closing comments. Speaker 500:24:55Eric? Speaker 200:24:57Thank you, Chris. We began the New Year with the 1st FDA approval from our rare disease pipeline. The accelerated approval of Vilspari marks the 1st and only non immunosuppressive treatment indicated for the reduction of proteinuria in patients with IgAN And I am very pleased with the execution so far in the launch. Most importantly, following the 1st 6 weeks of launch, We are well in line with our expectations for demand, patient access and reimbursement. And I am very pleased with how our team is executing on our launch plan. Speaker 200:25:30We will remain focused on building momentum as interest amongst nephrologists continues to grow And we look forward to providing regular quarterly updates on the Filspari launch. We also have a number of exciting milestones ahead of us this year. We look forward to the top line results from the PROTECT study in the Q4 of this year and remain highly confident in the final results achieving a statistically significant treatment effect on eGFR. As we know physicians are excited to see those data. We believe positive results will lead to traditional approval of And catalyze the next phase of growth. Speaker 200:26:05Furthermore, we are pleased with the ongoing EMA regulatory review and look forward to a potential approval of And finally, we are very excited about the opportunity in HCU. The HCU community has been highly underserved and they are eagerly seeking effective treatment options. Pegdebatinase has the Now, let me turn the call back over to Naomi for Q and A. Naomi? Speaker 100:26:41Thanks, Derek. Operator, can we now open the line for Q and A? Operator00:27:04We will take the first question from the line of Maury Raycroft from Jefferies. Maury, your line is now open. Speaker 600:27:13Hi, congrats on the progress of the launch and thanks for taking my questions. Based on The Lancet paper, PROTECT is powered at 90% to detect an underlying treatment effect of 2.9 ml per minute per year. So that translates to 5.8 ml per minute over Can you clarify if that is the delta versus irbesartan or is that only the sparsentan treatment effect? Speaker 200:27:40Maury, thanks for the question. I will turn that over to Chulo. Speaker 300:27:44Thanks Maury for the question. So to clarify, we have greater than 90 giving us a geometric mean ratio of 0.59. So when you put that on the anchor curve, it predicts a slope difference Close to what we originally modeled and it shows a very high positive predictive probability for a difference in eGFR slope Even with a modest size trial and I'll point you if you want more details, I'll point you to the anchor appendix so that you can actually do some of this analysis yourself. Speaker 600:28:32Got it. That's helpful clarification. And based on the new DUPLEX data And the view that IGAN is a progressive disease, is there anything additional you can point us to for how we should think about irbesartan ARM treatment effect size on EGFR in PROTECT. Speaker 300:28:52Well, remember the ervastartan ARM in PROTECT was already essentially optimized On RAS inhibition, they were at least 50% label, maxillary tolerated RAS. So essentially, they were treatment failures because they had persistent proteinuria despite this. And there was still an incremental reduction in proteinuria on those on Erb, but we had a 41% relative reduction in proteinuria compared to the erbasartan arm. So I would imagine that we can anticipate those on erbasartan to progress similar to what we've seen in other Studies may be slightly better and in the Tarpeo study they progressed at 6 ml per minute per year. Maybe they'll do Slightly better than that just because we had a slight reduction in proteinuria, but that is what I would say compared to the historical control. Speaker 600:29:41Got it. That makes sense. And maybe last quick question. Similar to DUPLEX, I'm wondering, do you have any feedback from FDA on whether it would be okay if you miss on total slope, but hit stat sig on chronic slope Speaker 200:29:59for Protect. Bill, why don't you take that question? Speaker 700:30:03So we don't have a specific dialogue from the See addressing that with PROTECT, in the discussions around the design of the DUPLEX study, they did say that in the end, While the study is designed around total slope first and chronic second, they certainly want to look at all the elements of the study. And I think that my expectation is they'd be consistent with each program, with that type of approach. Speaker 600:30:34Got it. Okay. Thanks for taking my questions. Speaker 200:30:37Thank you, Maury. Operator00:30:41We will take the next question from the line of Greg Harrison from Bank of America. Greg, your line is now open. Speaker 800:30:49Hey, good afternoon. Congrats on the FOSPARI number and thanks for taking the questions. Are you able to give any additional color on What part of the $3,000,000 sales number was patient demand and maybe how many patients are on treatment? And then What portion of the 146 patient start forms have transitioned into paying patients? Or At least maybe what should we expect that rate to be over time? Speaker 200:31:21Greg, thank you for the questions. We Would be in a position to be able to share as we mentioned at the approval to be able to talk about the Patient start forms as well as revenue, but we recognize certainly that early on in any phase of launch for specialty medicine, you're going to have Variability in terms of the stocking as well as how quickly you get that through. And I think as both Peter and Chris mentioned, it is going to take some time to have that while we did have some reorders or orders that reflect Underlying demand, you can largely think about that $3,000,000 as channel stocking for the Q1. And we are not going to be providing any specifics at this point with regard to the breakdown of or Conversion of Patient Start forms to reimbursement. They're very in line with our expectations. Speaker 200:32:21We're really pleased with all aspects of the launch so far. But those metrics really are lumpy in the first part of a launch and we want to make sure that we can provide a consistent set of metrics over time that are going to be predictable And consistent, throughout the launch. So stay tuned. We may evolve and being able to share some of that as we have an underlying trend emerge in the launch. But at this point, I would say that you should rely on the 146 reflecting the underlying demand from nephrologists. Speaker 800:32:50Okay. Fair enough. And then the $146,000,000 number, it's pretty impressive. I think it's above most Do you think that reflects at all a bolus of patients that was maybe waiting for treatment? Or do you expect more of a steady ramp throughout from here? Speaker 200:33:15Peter, why don't you take that one? Speaker 400:33:18Yes. Happy to do that Eric and thanks Greg for that question. Yes, you don't really see a bolus You have to realize IgA nephropathy is still a rare disease. Even though every nephrologist has at least a handful of IgA nephropathy patients, It's not like a physician has top of mind like, hey, all those patients should come in at a certain day. So I have to say, especially after spending some time in the field and seeing How busy those community practices are? Speaker 400:33:45IGA nephropathy for us is top of mind. But for nephropathy in all those patients they're serving, It's only a small, small threshold. So I don't think there's a bolus. We're happy with the steady demand that we're seeing and there's a building demand as well. But I wouldn't say there's a bolus of patients that you see initially. Speaker 400:34:03I think you will see a constant steady growing demand With regards to IGA and Pharmacy as patients are coming into the office as we progress in the launch. Speaker 800:34:15Okay, great. Thanks for taking the question. Speaker 200:34:18Thank you, Greg. Operator00:34:21We will take the next question from the line of Joseph Schwartz from SVB Securities. Joseph, your line is now open. Speaker 900:34:30Hi, thanks so much. I was wondering if you can give us any insight into how many physicians have written a filsparate prescription to date And if you can describe the earliest adopters for us? Speaker 200:34:43Peter, why don't you take that question? Speaker 400:34:48Yes. At this point, to your earlier point, we won't be disclosing like how many prescribers we have. We have seen Repeat prescriptions already. I think it's in line with what you may have expected given the 140 6 patient thought forms. We're very pleased with the way physicians are Receiving the product right now. Speaker 400:35:13And to your point, like what is the profile of the prescriber so far? Well, we have really been targeting based on 3 aspects. 1 is volume, patient volume in the clinic as well as the physicians' behavior in adaptation of new Innovation as well as the influence. And we see that especially the patients, the physicians And lost community practices are key to prescribed so far. Okay. Speaker 900:35:43Thank you. And then, maybe a question on your HCU program. We hear that these patients can be somewhat elusive. So I was wondering if you can describe Your relationship with the patient community and the physicians that treat them and how has that evolved since running the COMPOSE study? How challenging was that to enroll? Speaker 900:36:04And do you think how much of a challenge do you think it could be to enroll a larger Phase 3 study? Speaker 200:36:12Yes, Joe, thank you for the great question. I'll start by sharing a little bit about the relationship and how the community has evolved. And then I'll ask Jula to share Some of the insights that her team has gathered in conducting the COMPOSE study. This is a patient community that really has been underserved. And when we took over the program, many of them were actually served by connecting with phenylketonuria or PKU community because of a lot of the similarities and how the conditions are managed. Speaker 200:36:44But I think as we've started to really build our relationship with them, They really start to build their own community online as well as with kind of the standard patient advocacy organizations, Both here in the U. S. As well as abroad. And I think that we're starting to see a much more concerted and organized effort to articulate what the needs of that community are with regard to earlier diagnosis, improving newborn screening, Helping to understand better management of the disease as well as I think for us educating about the importance of engaging in the clinical trials as a So I think largely we've been really pleased with how quickly the community has evolved And I think we've really gained a lot of good learnings with regard to clinical trial enrollment. And with that, I'll turn it over to Jula Speaker 300:37:41Thanks, Eric. Well, any rare disease, it can be challenging to recruit because there's very few patients So it can take a bit longer and you often have to go to where the patients are and you really do need to engage with your advocacy partners and with the patient community to understand what's important to them, simplify the trial design and provide them a lot of support. And so that's what we're doing moving forward. I would say also importantly, We have significant engagement with the key opinion leaders to make sure that what's important to them and their patient community is what we incorporate into the design of the study. And then we also have a natural history study that helps us with having access to patients who if they're Speaker 400:38:33Thank you for the insights. Speaker 200:38:36Thanks, Joe. Operator00:38:39We will take the next question from the line of Carter Gould from Barclays. Carter, your line is now open. Speaker 1000:38:46Hey, this is Leon Wang on for Carter. Thanks for taking my question and congrats on the results. So, on Fospari, any early signs of the patient profile that docs are prioritizing versus those that they may be waiting for more confirmatory EGFR data or any profiles of docs that may be Perhaps waiting for data and not as receptive to the initial launch. Speaker 200:39:18Yes. Thanks for the great question. Maybe I'll start by saying with any launch, you typically will see A spectrum of adoption by physicians where you have some that are early adopters and those that are waiting. That so it's not surprising that there will be some physicians that want to wait. What I will say is that we're very pleased and the performance thus far from physicians is Absolutely in line with our expectations and also in my experience with launches. Speaker 200:39:48I'll ask Peter to share a little bit more about the types of patients that we're Seeing prescribed FOSFARI in the 1st 6 weeks as well as the profile physicians that we see adopting. Speaker 400:40:00Yes. Thanks, Eric. Happy to provide some color on the patients that we are seeing. So the majority, the vast majority of the patients Those patients that are on rapid path of progressing with consistent hypoximuria levels. Many of those Are above 1.5, but we also have some prescriptions for patients with lower proteinuria levels than 1.5, but have additional indicators for rapid progression. Speaker 400:40:26So I think largely in line with how the indication is written, nearly above 1.5 with some also below 1.5 gram per gram. Speaker 200:40:38Maybe the other thing that I'll Peter that I'll add is That the payer mix is very consistent with what we had assumed with the majority of these patients having commercial insurance. So I think A lot of the work that Peter's team did to really profile what this look like, what the launch update could look like It's again very much in line with our expectations and planning. Speaker 1000:41:04Great. Thank you. Speaker 200:41:06Thank you. Operator00:41:10We will take the next question from the line of Sabayko from Evercore ISI. Lisa, your line is now open. Speaker 100:41:19Hi, there. Thanks for taking my call Speaker 1100:41:21and congratulations on The initial good start here. What just I know you wouldn't have this right now, but as we think about sort of Later in the year, what kind of gross to net can we expect? What would it be initially? And I'm not saying about this quarter, but And then what do you think it will stabilize around? Speaker 200:41:43Yes, great question, Lisa. Certainly, as you alluded to, the first part of a launch It's going to be quite lumpy. So we've been reluctant to provide any estimates at this point, but I'll ask Chris to comment on where we think we may be landing once we get to that It's a steady state. Speaker 500:42:01Yes. Thanks for the question, Lisa. Really at stable state, we're going to be looking at mid to high teens. And I think what we're seeing now is reflective of us getting there once we do get to that stable state. So no change from our expectations on that point. Speaker 1100:42:17Okay. And then just back to the Protecta and your powering. So Jula, can you just clarify? So you saw a 2.9 so you're powered for a 2.9 Milliliter difference with slope, that was assuming 30% difference in proteinuria, but you actually got a bigger delta than that. So now You should have a greater difference. Speaker 1100:42:44Is that the right way to think about that? Can you just I didn't hear everything you said. It was a little confusing. Speaker 200:42:50Yes. Julie, would you like to take that? Speaker 300:42:54Well, our initial power calculation was based on historical data. And then you can map it based on the anchor data. So based on the anchor data, we fall in line with our original Power calculations to be able to predict a statistically significant and clinically meaningful effect at 2 years. The other thing I do want to add to this is that as part of our review for accelerated approval, the FDA was very focused That we would be able to confirm our benefit at the 2 years. So they asked us the likelihood of Achieving statistical significance both on the chronic and total slope endpoints for the 2 years. Speaker 300:43:34So we provided conditional power calculations that looked at our available eGFR data at the time of the interim as well as the information from the trial level analysis to address their request. And importantly, the conditional power calculations provide a very high level of confidence on achieving statistical significance at the 2 year confirmatory analysis. Speaker 100:43:57Okay. Thanks. Speaker 200:43:59Thanks, Lisa. Operator00:44:03We will take the next question from the line of Mohit Bansal from Wells Fargo. Mohit, your line is now open. Speaker 900:44:11Thanks for taking our questions. This is Speaker 800:44:12Adam on for Mohit. Speaker 900:44:14Could you discuss whether you think naive patients or patients switching to Filspari Is the bigger driver of demand in the 1st year of the launch? And then separately on the 3% of insured lives being covered, Is that ahead of your expectations? And how could we think about that going from here, the type of cadence from quarter to quarter? Speaker 200:44:36Sure. Peter, why don't you take those two questions? Speaker 400:44:43Yes. Hi, Peter Erik. Thanks for that question. So when you think about like where is the main demand coming from with regards to Speaker 800:44:51patients naive or switched, it is Speaker 400:44:51very consistent like the It is very consistent like the majority, the vast majority of those patients have been on ACE or ARBs in the past and are switched So I think that is quite consistent. I think ultimately you will start to see naive patients as well. I think It's a small fraction of the total patient population because the majority of those patients are prevalent already in the offices of the physician. So what we are seeing right now is much of that phenomenon, patients that have not been managed to the proteinuria levels at the physician once And ACE or ORCs are being replaced with skilled flowery. So that was the first part of your question. Speaker 400:45:35With regards to the 2nd part of the 38% coverage, it's a good number and it's not in line with Expectation, especially if you take into consideration that it was only after 6 weeks. So 38% coverage by March 31. I think it's a good number that we feel quite proud of and I think it's at the high end what you see with Benchmark products. Speaker 200:46:00Yes, Adam, thank you for that Peter. The only thing I would add with regard to actually both of those questions is the quality of the Payer coverage, it's really important to think not just about coverage, what's the quality of the coverage relative to the labeled indication and we're really pleased to see There's a high degree of quality when we think about the access for patients aligned to the label. And we do see a number of those payers that have stepped through ACE or ARB. But again, as Peter alluded to, the majority of these patients are already on ACE or ARB. In fact, many of these patients are referred to their nephrologists on ACER ARB. Speaker 200:46:40So when we look at the actual quality of the coverage, it's not just the 38%, but it's actually the quality of that access and we're really pleased. Again, early days, but I think it's a great foundation upon which to build throughout the rest of this year. Operator00:47:04Any further questions, sir? We will take the next question from the line of Laura Chico from Wedbush Securities. Laura, your line is now open. Speaker 100:47:18Thanks very much. I guess I wanted to talk a little bit more about the cadence of Ordering here. And I guess Eric maybe said differently, could you just walk us through what are the expectations around the timing From receipt of a start form to when product is actually going to be dispensed, like what is the timeframe there? Sorry if I missed it. Speaker 200:47:42Yes. No, it's a great question, Laura. And it's an important dynamic to think about any specialty launch, where there is a range of timelines for from prescribing. And I'll ask Peter to talk a little bit about what we're seeing and also what we Expect to see throughout the rest of this year. Peter? Speaker 400:48:05Yes. I'm happy to respond to that. Thanks, Laura, for that question. I think to Eric's point, as is typical for many rare disease product launches, there's a wide range of what I call the time to fulfillment, especially in the early days as payer access may take longer. Some would say in these early days, the sales party time to We anticipate that this pull through will decrease as we get more payer coverage. Speaker 100:48:42And I'm sorry, Peter, just to verify, you said it's ranging from 20 to 60, but over time would likely to be closer to a typical 30 day range. Do I have that correct? Speaker 400:48:51Well, let me clarify that, Laura. I was talking about what is common in rare disease in general, but I would say, we are in that range. It's more historically what I've seen in rare disease and specialty launches. So this is not reflected on shelf Speaker 200:49:09Understood. Yes. I think the important aspect, Laura, to keep in mind is the we won't provide any specific numbers because it really is only the 1st 6 weeks of experience after approval, what's important is as we get more broader coverage and high quality coverage, That lead time should shrink. And I think what's important in the experience that Peter's team has had is that we've already one, we're Off to a great start with regard to payer coverage and reimbursement, but we're already starting to see that average time to fill Reduce. And I think that as Peter's team continues to execute and we continue to get growing coverage, We'll continue to see that average time as well as the range reduced. Speaker 200:49:57So again, really early days, so we don't want to give numbers because it is lumpy. But the dynamics that we're seeing are exactly what you would expect to see with this successful launch. Speaker 100:50:08Okay. That's helpful. And maybe I'll Speaker 400:50:10sneak in one quick follow-up Speaker 100:50:11And again, apologies if I missed this, but did you quantify yet how many physicians have signed up for the REMS at this point? Speaker 200:50:20Peter? Speaker 400:50:22Yes. No, we haven't given a number there, but we're very pleased as with the patient's platform. So we see Steadily increase in ramp certifications and enrollment. And I think it speaks to the physicians that they understand The value that COSPARI may have for their patients, but also that I understand that the REMS Operator00:50:53We will take the next question from the line of Tim Lugo from William Blair. Tim, your line is now open. Speaker 1200:51:01Hey, guys. This is Lachlan on for Tim. Thanks for taking the questions. So I guess heading into the launch, one of the headwinds you guys had mentioned Well, potential headwinds was just that physicians wouldn't really have wouldn't know the data very well because it's obviously not much had been released. So I'm just wondering how much I guess, how that has played into the launch so far? Speaker 1200:51:24Have you seen That sort of affecting any of the interactions or the speed at which physicians are maybe starting to prescribe? Or is that really Not affecting that rate, I guess, compared to what you expected. Speaker 200:51:41Yes. It's a great question, Lachlan. I think First, I'll point to what Jula mentioned in having a high profile publication Of the interim data that I think really gives physicians a better understanding about the data. But Peter, why don't you share a little bit more about what Hearing from your team about going through the data on Gylfari. Speaker 400:52:07Yes. Happy to do so. So indeed, nephrology in general is not as much inclined with innovation as maybe some other specialists, Given that there has been so little innovation to nephrology in general. And I think that's a phenomenon that we have seen with other Neufrology launches, in particular rare launches. To Eric's point, I think having new data and this is kind of like a rolling launch because we launched In the 1st 6 weeks without having a publication or without having further data, which is not very common to launch a product without that specific. Speaker 400:52:43So we lost basically on the PI also given the promotional restrictions in the Software AG's products with Brazilian accelerated approval. But now that we have the lens of publication and you start to improve you in Medellin guidance like UpToDate and As Joanna mentioned in her part of the prepared remarks, I think that further provides confidence and provides more insights in that process as well. So I think we I'm very pleased what I'm seeing, both on the intent to prescribe, but also on the actual prescriptions already, and that's the 146 patients for the river in Lolito. I think as we get more data and we have those publications, this will continue to have Bring confidence to the Pharosy community and allow for continued and accelerated scripts. Speaker 200:53:35Yes. I think that's absolutely right, Peter. And I Share with you, 2 maybe additional observations. And like Peter, I spent quite a bit of time in the field Meeting with customers, I think there's a real eagerness to understand the profile and the data of Filzpari more. So the Publication and guidelines are going to really help provide some of that independent or third party perspective. Speaker 200:54:03But the other aspect is that it really helps understand the REMS better and the profile of A low rate of ALT, AST elevation because I think in the absence of that information, it was hard for physicians to put into perspective what the Full of risk really is and I think it's been very reassuring for physicians when they see the actual rates in the publication and in the label. Speaker 1200:54:32Got it. Thanks. And on the topic of reimbursement, I think you mentioned that most of it had gone through, but there were some delays for the patients that you're seeking reimbursement for. I guess to the extent that there have been delays, Can you maybe talk about what pushback you're getting from payers? Speaker 400:54:54No, I wouldn't say it. I mean, as you don't have inclusion in the formulary yet, I mean, it goes through the prior authorization pathway. So that generally takes a lot. I mean, I think that's a common process in rare diseases in particular. So I wouldn't indicate this as like particular obstacles that we are seeing for Phil Starry. Speaker 1200:55:18Got it. Thanks. Speaker 200:55:20Thanks, Auchlin. Speaker 100:55:23We will Operator00:55:24take the next Question from the line of Vamil Divan from Guggenheim Securities. Vamil, your line is now open. Speaker 1300:55:32Great. Thanks for taking the questions. I think most of mine on the launch have been answered, but I just or asked and answered. But just one more, just in terms of the patients that are getting So far, obviously, it is early. I'm trying to get a sense that you mentioned sort of the ASINR dynamic. Speaker 1300:55:48But in terms of SGLT 2, if you can comment on narvelesside patients already on SGLT2s or not? And also curious with the label mentioning the greater than Particle 1.5 gram per gram, is that sort of metric that physicians seem to be sticking with? Or are they just using their judgment and maybe And then the second question is more on the expense side, I guess, for Chris. Just How we should think about, especially SG and A, the spin this quarter, Q1 was a little bit more than we were expecting. Is this sort of A reasonable amount to assume going forward or is there still a little bit of buildup, we should expect sort of higher ramp up as we get into 2Q and 3Q this year. Speaker 1300:56:32Thanks. Speaker 200:56:34All right, Pavel. Thanks for the questions. Peter, why don't you take the first on the patients? Speaker 400:56:41Yes, it's a good question. Maybe I'll start answering the question by giving a broader perspective on the patient profile Because this is often a younger patient population, right? Many of those patients are being diagnosed in the late teens, early 20s. And that's what we are seeing as well, many young patients that are on a path of rapid progression. And to your point, Right. Speaker 400:57:02What we're seeing is many of the current available medication doesn't bring patients to the level to the target level that physicians would like to see. Jason, Arps didn't do that. We have SGLT2. I think that's something that you mentioned as well, and we see that increased utilization in SGLT2. The physicians feel very comfortable in combining if needed or if appropriate with SGLT2 as It's mechanistically synergistic, but also sales firing has that very rapid progression of 50% First, I know we are rushing that physicians haven't seen risk other medication, especially the non immunosuppressive nature of chilSpari With or without combination with SGLT2 makes physicians very comfortable, especially when you talk about the younger patient profile That have been yes, the side effect profile of immune suppression is not very pleasant, especially for this patient population. Speaker 200:58:04And Chris for expenses. Speaker 500:58:06Yes, absolutely. Thanks for the question, Vamil. What I would point back to is in the prepared remarks Talked about for overall expenses, we anticipate moderate increases for the balance of the year. And really when I think about the breakdown of SG and A and R and D, That's probably more pointed towards R and D as we look to continue both the DUPLEX and PROTECT studies that are going to continue on for the balance of the year, But then also the pegmatinase work that's going to go into the potential initiation of a Phase 3 as well as the supply CMC work that all needs to be done to Scale up for both Phase 3 and commercial. And so I think that's where you'll see likely the larger magnitude of increase come for the year. Speaker 500:58:43I think from an SG and A perspective, There may be some modest increase from this point, but I wouldn't expect it to be of any significant magnitude. And really what we've gotten to And this Q1 is the first time in which you've had the full sales force fully in place, doing all the promotional activity and Putting that right investment behind Filspari to make sure we can position it appropriately for IGA. Speaker 1300:59:09Okay, great. Thank you. Speaker 200:59:12Thank you. Speaker 100:59:14We will Operator00:59:15take the next question from the line of Alex Thompson from Stifel. Alex, your line is now open. Speaker 1400:59:22Hey, great. Thanks for taking my questions. I got one iYan question and one FSGS question. I guess on iYan, I'll try to ask another sort of commercial dynamics question. I guess given that you're starting by targeting a lot of higher volume prescribers, Speaker 400:59:35can you talk a Speaker 1400:59:36little bit qualitatively about whether A majority of the start forms that you're seeing so far coming from single physicians or multiple physicians writing Multiple start forms for patients or is it broader than that? And then on FSGS, can you comment on sort of In rare disease especially. Thanks. Speaker 201:00:06All right, Alex. Thanks for the questions. Peter, would you like to take the IGAN question? Speaker 401:00:13Yes. Thanks, Alex. So if I understand your question correctly, your question was like do you see mainly Prescription from prescribers that have multiple prescriptions or more single and if it's mainly in the higher volume centers. Speaker 1401:00:30I think it's too Speaker 401:00:31early to make a specific statement on that. I think we see The majority of the prescriptions coming from community centers, especially from larger community centers, but we also see prescription from academic centers. And we see a mix of Physicians that have prescribed a single time or a second time. So but again, it's early days. I'm prescribing this I'm describing this for the 1st 6 weeks, so I wouldn't be too much into it. Speaker 401:00:58We see a large prescriber base and we see both single as well as multiple prescriptions Speaker 201:01:08And Bill, why don't you take the question on regulatory flexibility? Speaker 701:01:14Yes. No, happy to. I think the one that comes to mind quickest is Entresto for congestive heart failure It was approved by Cardio Renal, I think in 2021, if my memory is right. And that was a drug that missed their primary endpoint, but the decision in the Agency was that there was clear benefit and across the trial based on totality of evidence and unmet need That was something that they were interested in approving. I think that there have been other instances across Rare disease indications and I think the most recent work that I read was in JAMA where they said in about the past 5 or 10 years, about 10% of the drugs approved by the FDA were ones that missed their primary endpoint In their pivotal studies. Speaker 701:02:06So it's not the norm, but it's also not something that's unheard of. Speaker 201:02:12And, Julie, anything further that you'd like to add on that question? Speaker 301:02:18I would also point to Fabry It's another potential indication for megalinostat to look at as another reference. Speaker 1401:02:28Great, helpful. Thanks so much. Speaker 201:02:31Thank you. Operator01:02:34We will take the next Question from the line of Ed Arce from H. C. Wainwright. Ed, your line is now open. Speaker 1501:02:41Great. Thanks for squeezing me in here and Congratulations on the early progress on the launch. I see here, obviously, 1st 6 weeks, $3,000,000 is, as you said, represents mostly stocking and 146 PSFs, mostly demand. And I recognize as you pointed out that it's highly variable at the beginning. But I'm wondering as we get through the next few quarters And Nir, if there are specific launch metrics that you intend to report regularly, for example, we've already discussed Sort of the fulfillment conversion rate or number of prescriptions or patients on drugs and then perhaps later Numbers around persistence or compliance rate. Speaker 1501:03:34And just so that's first. And then secondly, just wanted to ask as well on The readout later this quarter in HCU with the higher dose and the lyophilized formulation. The focus clearly is at least partly on the efficacy look From that dose as well as the PK with the new formulation, but what other aspects to the data readout Could we expect later this quarter? Thanks so much. Speaker 201:04:09Yes. Thanks Ed for the great questions. I'll take the first one. So I think we certainly can are looking at a number of different metrics. And it's important for us to make sure that the metrics that we provide regularly are ones that we have confidence in the sort of trendability and the predictability. Speaker 201:04:28We believe that's why we've focused on patient start forms and access because they really are robust predictors of underlying demand as well as the ability to pull through and have those reimbursed. I think as we look forward, you can imagine that there may there likely will be others like The persistence rates or the reimbursement rate and you can look to our commercial business where we have talked about Persistence, the high rate of persistence, etcetera. So as we start to understand the underlying dynamics of the Filsparin launch, We'll look to evolve what those are. But again, we want to make sure that we really focus on those fundamentals this year that we believe are going to be most important in the 1st year of launch. And then with regard to the readout of the Cohort 6 in the COMPOSE study, Bill, I'll turn to you to provide some further perspective on what we'll be looking for and possibly what we would be Disclosing, but I will say we haven't yet committed to what we will disclose specifically. Speaker 201:05:36Bill? Speaker 701:05:38Sure. The Cohort 6, we utilized the highest dose to date on a mg per kg basis In the study, in what we view as the final cohort in the COMPOSE study, it also gave us the opportunity to utilize the lyophilized Formulation and evaluate that in patients. What we're looking for is the most predominant biomarker It's going to be the reduction in homocystinuria or in total homocystine over time in the 12 week double blind portion of COMPOSE. In addition to that, of course, we're looking at safety and tolerability. It's a Phase onetwo study and evaluating that for those Individuals at that dose and those patients will roll over into the open label Speaker 401:06:27extension Speaker 701:06:28that will give us the data then to select a dose and help us with the design of the Phase 3 study. Speaker 1501:06:38Sounds good. Thank you so much. Speaker 901:06:40Thank you. Operator01:06:43There are no further questions at At this time, Ms. Eichenbaum, I will turn the conference back over to you for any additional or Speaker 401:06:51closing remarks. Speaker 101:06:52Thank you everyone for joining us for our Q1 2023 financial results call. We look forward to providing additional updates on our progress. Have a great rest of your day and thank you. Operator01:07:04This concludes today's call. Thank you for your participation and you may now disconnect.Read morePowered by
